Decompose (Mogrit's Technomancer's Textbook)

This spell rapidly causes the body to decay. There are two possible uses for the spell, depending on whether the target is a living or dead creature. If you cast this spell targeting a living creature, make a melee spell attack against a creature you can reach. On a hit, the target takes 4d8 necrotic damage. If you cast this spell targeting a dead creature, the body rapidly decays, increasing the amount of time the creature has been dead by 10 days for the purposes of the time limit on raising the target from the dead. For example, a dead creature targeted by this spell could not be returned to life by the raise dead spell.

At Higher Levels. When you cast this spell targeting a living creature using a spell slot of 3rd level or higher, the damage increases by 1d8 for each slot level above 2nd. If you cast this spell targeting a dead creature using a spell slot of 5th level or higher, the amount of time the creature has been dead increases to 100 years. If you cast this spell targeting a dead creature using a spell slot of 7th level or higher, the amount of time the creature has been dead increases to 200 years.
